Biotechnologies from Marine Bivalves

Abstract

Bivalve molluscs comprise more than 9000 extant species. A number of them are traditionally farmed worldwide and are fundamental in the functioning of benthic ecosystems. The peculiarities of marine bivalves have inspired versatile biotechnological tools for coastal pollution monitoring and several new biomimetic materials. Moreover, large amounts of sequence data available for some farmed bivalve species can be used to unveil the organism's responses to environmental factors (e.g. global climate change, emergence of new infectious agents and other production problems). In bivalves, data from genomics and transcriptomics increases more quickly than data from other omics, and permit new bioinformatics inferences, real comparative genomics and the study of molecules suitable for biotechnological innovations. Bivalves (and their microorganism communities) produce a variety of bioactive peptides, proteins and metabolites. Among them, the numerous families of antimicrobial peptides identified in the Mediterranean mussel likely contribute to its vigour and could assist with the identification of molecular scaffolds for innovative pharmaceuticals, nutraceuticals and constructs suitable for other applications.

Phytochemical composition, total phenolic content and antioxidant activity of Anadara granosa (Linnaeus, 1758) collected from the east coast of South Sumatra, Indonesia

“…Anadara granosa is a group of the family Arcidae, a class of bivalves, mollusk phylum known for a long time 5 . Marine mollusks have been reported to have biological activity because they contain a variety of bioactive compounds, such as gastropod groups in mangrove vegetation 6 and coral reef ecosystem 7 , and the marine bivalves group 8 . Bioactive compounds produce essential biological activities in the form of antioxidant abilities that are attracting attention today.…”

The effect of the abundance of venus clams (Gafrarium tumidum Röding, 1798) on sediment accretion in the sandy intertidal of Pari Island

“…The widely known autogenic engineer is reef-building bivalves such as mussels (Mytilidae) and oysters (Ostreidae). Their physical structure can primarily alter the sedimentary habitat [5]. In addition, they create fecal and pseudofaecal biodeposits that build up in the reef and its surroundings as filter feeders [6][7][8].…”

Diversity of bivalves on the north coast of Lamongan, East Java, Indonesia

“…The Bivalves have a fairly high economic value (Boominathan et al 2008;Santhiya et al 2013;Van Der Schatte Olivier et al 2018), some of which can be used as a food source (Gopalakrishnan and Vijayavel 2009;Biandolino et al 2019;Wijaya and Ambarwati 2021) because of their delicious taste and high protein content (La Valle et al 2011;Admodisastro et al 2021). In addition, coastal communities also use bivalves as ornaments (Santhiya et al 2013;Sahidin et al 2019;Venier et al 2019). Its potential economic value can lead to overexploitation.…”
